Moving to Tucson Metro
Tucson Metro is served by Tucson International Airport and I-19 (running south from Tucson through Green Valley toward the Mexican border), with I-10 connecting Tucson to Marana and, further north, Casa Grande and Phoenix.

I-19 runs south from Tucson through Sahuarita and Green Valley toward the Nogales border crossing, roughly 70 miles from Tucson proper. I-10 runs northwest from Tucson through Marana toward Casa Grande and Phoenix -- Marana's fast growth (up 28.95% since the 2020 Census) is directly tied to this corridor's new master-planned-community construction. Oro Valley sits north of Tucson via Oracle Road (AZ-77) rather than a direct interstate connection.
Tucson International Airport Serves the Entire Region
Tucson International Airport (3.9 million FY2025 passengers, 19 nonstop domestic destinations) is this region's shared air-service point -- a real, actively growing regional airport, but genuinely smaller in scale than Phoenix Sky Harbor's national-hub status. Expect more connections than nonstops for travel outside the Southwest.
Water Supply Varies by City Within This Region
Water sourcing differs meaningfully by specific city: Oro Valley draws its full Central Arizona Project entitlement (roughly 10,300 acre-feet) rather than leaving some in the river, as some Phoenix-area cities have offered to do -- a real, disclosed water-policy fact worth weighing directly. Marana, by contrast, holds only a small historical CAP water contract and leans heavily on groundwater plus a one-time, roughly one-year groundwater allowance -- a real, disputed local sustainability question tied directly to the town's fast growth.
Confirm School District Access Before Choosing a Specific Community
Green Valley hosts essentially no schools of its own, relying entirely on the Sahuarita Unified School District's Sahuarita-based campuses -- a real, practical consideration for any family with school-age children considering Green Valley specifically rather than nearby Sahuarita. Oro Valley's own school picture is genuinely mixed by campus (a top-tier charter elementary alongside a more middling district high school), so confirm the specific zoned school for a target address.
Key takeaways
- I-19 connects Tucson south through Sahuarita and Green Valley toward the border; I-10 connects Tucson northwest through Marana toward Casa Grande and Phoenix; Oro Valley connects via Oracle Road rather than a direct interstate.
- Tucson International Airport serves the entire region as a real, if regional-scale, airport -- genuinely smaller than Phoenix Sky Harbor's national-hub network.
- Water supply varies meaningfully by city -- Oro Valley draws its full CAP entitlement while Marana relies heavily on groundwater with only a roughly one-year exhaustible allowance, a real, disputed sustainability question tied to its fast growth.
- Green Valley has essentially no schools of its own, relying on the Sahuarita Unified School District -- a real, practical consideration for families with school-age children.
